For everybody who contradicted me about the fact that the leg shouldn't trail behind you in a sprint:

?????

What are you talking about?

First of all, he seems to be implying that trail leg being further back is WORSE, and that his trail leg was not trailing back.

Secondly, what he said made no fucking sense. Johnson in that still was simply in a different phase of his stride . . .he's comparing apples and oranges there.
"Performance during stretch-shortening cycle exercise is influenced by the visco-elastic properties of the muscle-tendon units. During stretching of an activated muscle, mechanical energy is absorbed in the tendon structures (tendon and aponeurosis) and this energy can subsequently be re-utilized if shortening of the muscle immediately follows the stretching. According to Biscotti (2000), 72% of the elastic energy restitution action comes from tendons, 28% - from contractile elements of muscles.

Nah, the best sprinters don't let their leg fly back behind them. They do the leg curling action pretty much under them, not behind them. It's that thing with "imagine it's a glass wall behind you".

Technique is hugely over-rated when it comes to running. Look at 3:25-4:04 at the Jamaican schoolboy champs in that video. All of those runners have technique that looks horrible yet they are running elite times for their age. A year after this vid was made Michael Johnson came out and declared that black people were fast from slavery. Sure technique helps and the more efficient you are the faster you're going to run but it's easier just running the way you naturally run and not thinking about it. Use a few cues but don't get obsessed over what your body is doing because your legs follow your arms. Until you're at an elite/world class level and need to worry about that stuff it's not even worth worrying about. Just put in the time at the track and put in the metres and you'll always improve much faster than the guy doing a quarter of the workload stressing out about technique. Another thing about Michael Johnson is that his technique was considered awful and the polar opposite of textbook, however it worked. In fact he ended up choosing his college and coach because that was the only coach from the colleges who were interested in him that didn't want to change the way he ran.

wow. what bullshit. it just amazes me how STUPID most coaches are, and how stupid exercise science can be. I'm taking a biomechanics class right now, and we're being taught completely wrong bullshit.



But again to respond to your point Raptor, your leg may be behind you at one point in your stride, but as it cycles, it will move to under the hip...
<a href="http://www.youtube.com/watch?v=QHG5vB8hX4E" target="_blank">http://www.youtube.com/watch?v=QHG5vB8hX4E</a>

pause at any point during the race and watch how his leg trails behind him. pause at 00:24 for instance. In fact with his form he probably has greater backside mechanics than other sprinters. I think T0dday would be able to answer that well.


Again from personal experience, the best way to improve running form is from sprinting at top velocity but if running form isn't good there, working on heavy runnign specific strength training exericses, like single leg hypers.

Survival of the fastest
Why descendants of slaves will take the medals in the London 2012 sprint finals


Olympic champion Michael Johnson says black American and Caribbean sprinters have a 'superior athletic gene'

All eight finalists in the 2008 Olympic 100m final are believed to have been descended from slaves

Legacy: Michael Johnson, pictured in Jamaica, says black American and Caribbean sprinters have a 'superior athletic gene'

Olympic legend Michael Johnson says a ‘superior athletic gene’ in the descendants of West African slaves means black American and Caribbean sprinters will command the sport at the London Games.

The Olympic gold medallist and BBC commentator said: ‘Over the last few years, athletes of Afro- Caribbean and Afro-American descent have dominated athletics finals.

‘It’s a fact that hasn’t been discussed openly before. It’s a taboo subject in the States but it is what it is. Why shouldn’t we discuss it?’

Reigning Olympic 100m champion Usain Bolt was born in Trelawny Parish, Jamaica, where British Olympic boss Lord Coe’s plantation-owning ancestor George Hyde Park had 297 slaves.

Of the eight 100m finalists four years ago, three were Jamaicans, two came from Trinidad and Tobago, two were Afro-American and one, representing the Netherlands, was born on the Dutch Caribbean island of Curacao. All eight are believed to be descended from slaves.

Johnson says: ‘It is currently being researched to see how much of a factor being descended from slaves contributes to athletic ability.’


Taboo: Usain Bolt (right), pictured winning the Olympic 100m final in Beijing in 2008, was born in Trelawny Parish, Jamaica, where British Olympic boss Lord Coe¿s plantation-owning ancestor George Hyde Park had 297 slaves.

Some scientists believe a combination of selective breeding by slave owners and appalling conditions meant that only the strongest slaves endured, creating a group predisposed to record-breaking athletic performance.

African slaves underwent a rigorous selection process and only the fittest were transported on ships.

Interestingly, the toughest journey was to Jamaica, the last stop on the slave trail.

 During one voyage in 1732, a staggering 96 per cent of slaves lost their lives – 170 boarded the ship and only six got off.

Jamaican geneticist Dr Rachael Irving said: ‘There was not much oxygen on slave ships so they had to use whatever they had to survive.’

Dr Herb Elliott, doctor to the Jamaican Olympic team, added: ‘Only the most aggressive and fiercest slaves ended up in Jamaica.’

Johnson, 44, had a DNA test for a Channel 4 documentary, Michael Johnson: Survival Of The Fastest, to be screened on Thursday night, which confirmed he is of West African descent.

He said: ‘All my life  I believed I became an athlete through my own determination, but it’s impossible to think that being descended from slaves hasn’t left an imprint through the generations.

‘Difficult as it was to hear, slavery has benefited descendants like me – I believe there is a superior  athletic gene in us.’

wow. thanks for sharing.

I have heard of that theory that the toughest slaves were dropped off in jamaica..it's no doubt that Usain Bolt's genetics are superior. He can add mass easily, and he's fast... i dno if anyone has noticed, but the amount of mass he has on his arms is actually pretty decent, considering his ectomorphic structure.



and yea once again, wow what a hypocrite, if Johnson is saying all that, then pretending as if he understands why he was a better runner than others based off of some incorrect observations about the trail leg.

I agree with Michael Johnson that the theory could have some merit. That said I don't think he's a hypocrite for saying that and than running an athletics centre. He's just a businessman capitalizing off his athletic success like a lot of other athletes do. Besides he'd probably have a lot more knowledge than the majority of the other performance centres and 'speed camps' that are out there. When people go to those places or fork out money to train at some new age technological facility I think they're expecting some magical insights or secrets. If the facility just told them to go off and work on their speed, endurance, flexibility and strength they'd walk away disappointed so they have to come up with some biomechanical theories and fancy technology and place a lot of emphasis on technique so the clients walk away feeling as though they're getting their money's worth.

In my country the 200m and 800m national records have stood since 1968 despite all these advances and technologies and understanding in science etc. like the video below demonstrates.
<a href="http://www.youtube.com/watch?v=WiLeNvQmmyw" target="_blank">http://www.youtube.com/watch?v=WiLeNvQmmyw</a>
You'd think that after spending tens of millions on all of these start of the art facilities and with all the information and expertise that we'd be smashing those performances by now. Yet we haven't. 1 of my training partners used to train with a 400m Olympian (Mark Omrad) that spent 2 years training at the AIS. Anyway after 2 years of training at the AIS he moved back to Adelaide because he was overtrained and constantly getting injured and had gone backwards. He comes back to Adelaide and starts training 4x a week with moderate volume and ends up smashing his PBs in every distance from 100m through to 400m. Even our state facility SASI has a lot of similar cases because they do exactly the same thing as the AIS- get exercise physiologists and 'experts' to come in and train athletes. They put them on all these 'scientific' programs and overtrain the athletes and the athletes end up getting nowhere because in sprinting often the golden rule is less is more. Maybe you could argue that the overtraining at the facilities led to the PBs down the track but more often than not you just wonder why the investment isn't getting the athletes anywhere.

That's pretty interesting Mutumbo

Yes he's a businessman but still is wrong when talking about the trail leg... did you guys even watch the video I posted? His trail leg is more behind than other sprinters since his backside mechanics are greater.
